. IMPROVEMENT IN WATER-ELEVA'ILORS.

Specification forming part of Letters Patent No. 146,086, datcd December30, 1873,' application filed O-tober 4, 1873.

To all/whom it may concern Be it known that I, DRURY J. MGMILLEN, ofChillicothe, Livingston county, Missouri, have made and invented a newand useful Improvement in Water-Elevators, of which the following is aspecification:

The invention relates to that class of Waterelevators that are chieflyused for drawing water from wells. It consists in providing a frame, tothe sides of which are fastened uprights, provided near their upperextremities with cross-pieces, in which are the bearings of twohorizontal parallel metallic bars, upon each of which is secured acylinder or capstan, to which is attached a rope, the lower extremityhaving secured to it a bucket. Pivoted to the upright, adjacent to thecrank hereinafter mentioned, is a lever, through which pass the twohorizontal bars, one on either side of the pivot, being arranged so thatthey t'urn freely. The bearings of the horizontal bars toward thewindlass are open, so that by elevating or depressing thepower end ofthe lever one of the bars will be raised and the other lowered.

The crank is of usual construction, its axle being secured to theupright near it. It has attached to its axle a gear-wheel, which isarranged with relation to two smaller gearwheels, that are rigidlysecured to the ends of the metallic rods, the three wheels being soplaced that the direction of the revolution of the cylinders or capstansupon the bars may be reversed by means of the lever, as will fully Yappear hereinafter. Thus the crank may be turned continuously in onedirection, and, by

operating the lever, the buckets alternately raised and lowered.Directly below the rod nearest the front of the frame, or below thecenter ofthe space between the two upper rods, is a third metallic rod,which is rigidly secured at either side of the frame to uprights thatare fastened to the frame below, and assist in sustaining thecross-pieces above mentioned. Upon the rod last aforesaid turn twofriction-rollers, which are in proximity to the capstans, and serve todirect the ropes and buckets thereto attached. The bucket is constructedwith bent arms that, projecting upward, occupy places upon its rim inthe plane that is at right angles .to that which passes through the earsthat are provided for the the adjacent arm of the bucket `when being`elevated, is a rod that, extending thelength ofthe trough, turnsfreelyin apertures cut in the sides of the frame, its ends being bentand conformed accordingly. As the bucket is elevated the arm catches therod last described,

which is raised with the bucket, the latter tipping, gradually andgently, and discharging its contents into the trough, `which `havingbeen effected the direction ofthe revolution of the capstan is reversedby means of the lever, whereupon, the bucket descending, the arm isdisengaged, when the rod falls into position to receive the otherbucket.

The object of the invention is to provide a convenient and effective andrapid means of 4elevating water, especially adapted to wells orcisterns.

Figure l is a front view ofva device embodying my invention, partly insection. Fig. 2 is a side view, showing the relation'sgof the gearwheels.

A is the frame, which is preferably of rectangular shape, to the sidesof which are se` curely attached the uprights B B', near the upper endsof which are the cross-pieces C C', which are rigidly fastened to theuprights. D D are the two horizontal metallic rods, the ends of whichrest, respectively, in boxes or covered bearings in the piece C and inopen bearings in the piece C', being provided with the buttons c toprevent their dislocation. The bars D D are permitted to project beyondthe piece C', and gear-wheels EE` are rigidly attached upon theprojections, in such position that they engage each other, and thateither may be raised clear of the gear wheel O, which engages both ofthe Wheels E E when in their lower position. H is a horizontal le* ver,that is attached to the upright B by the pivot h, and through aperturesin which pass the rods or bars D D', the apertures and other parts beingof such size and so constructed as to permit the bars to turn freely.The power end of the lever I-I is carried out so as to be easilycontrolled by the operator at the crank. Upon the rods D D are fastenedthe hanged cylinders or capstans I I to which are secured the ropes K Kat the ends of which are the buckets L L. Below the rod D, supported bythe uprights d, which are attached to the frame and rest against the;4uprights B B and assist in supporting the cross-pieces G C', is the rodM, which is parallel to the rod D, upon l which rotate and slide thefriction-rollers e,

over which pass the ropes K K', the rollers being placed opposite' andbelow the capstans I I. N is the crank, which, in the present instance,consists of a wheel provided with a handle, the axle of which turns in abearing in the upright D and that part ofthe frame adjacent thereto.Sufficient space being left for it, the gear-wheel O is rigidly attachedto the axle of the crank immediately below the wheels E E.

The diameter of the wheel'O is greater than that of the wheels E E, toeffect a rapid revolution of the capstans I I. Between the wheel O andthe frame is the ratchet-wheel n and pawl m, which are attached,respectively, to the axle of the crank and frame. L L are the buckets,which have the ears p, to which the handles are attached, fastened belowthe middle of a vertical plane drawn from the rim to the bottom; andupon the rim in the planethat is, at right angles to that which passesthrough the ears p-are the bent or hooked arms s, that project above therim, being firmly secured thereto. Attached to the inside of the frontside of the frame is the trough Q, pro vided with a spout which directsthe water as may be desired. Upon the front edge of the trough rests therod It, the ends of which are bent, and turn freely in apertures in thesides of the frame. It is so placed that, when undisturbed, it extendsbeyond the edge of the trough its entireY length, resting thereon, andso that the arms s will catch it when the vbuckets are raised, and sothat, upon the arms being disengaged, it will fall into its naturalposition upon the trough.

The bucket L being in the well, the crank N is turned, thus elevatingthe bucket L and loweringl the bucket L. As the bucket L is drawn up,the arm s engages the rod It, and

the two rising together, the bucket is gradually tipped toward thetrough Q until its contents are delivered therein, when the arm sdisengages itself, the rod B falls forward into its place, and thebucket rights itself. In the mean time the bucket L has been lowered,and its elevation must be effected by the wheel E', the bucket L beingcontrolled by the wheel E. Power is now applied to the lever, whichdisengages the wheel O and throws the wheel E in gear with the latter.Motion is thus no longer communicated directly to the wheel E by thewheel O, but indirectly by the wheel E', so that the direction of therevolution of the wheels E E is reversed in both cases. Thus, withoutchanging the turning of the crank, lowering the ascending and raisingthe descending bucket, the adjacent arm of the latter of which catchesthe rod B and causes a delivery, as above described, when the lever isagain applied with like effect.

In the construction of the buckets, the bottoms or lower parts should bemade of such weight that they will right themselves, after being tipped,of their own weight. The rod B should, also, be so constructed that itwill fall across the edge of the trough, of its own weight.

If it be desired, a single capstan and rope may be employed, by coilingthe rope around the capstan in Adifferent directions, a bucket beingattached at each end 5 but the device described is to be preferred.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The gear-wheels E E', arranged lto engage each other in the mannerspecified, and secured to the rods D D', operating vertically bythe'action of the lever H, and provided with the flanged capstans I I incombination with the sliding friction-rollers e, substantially as shownand described.

In testimony that I claim the foregoing improvement in water-elevators,as above described, I have hereunto set my hand and seal this 29th dayof September, 1873.
